CLAMP FOR PIPES, SHAFTS, 80C.

SPECIFICATION forming part of Letters Patent No. 630,641, dated August8, 1899.

Application filed June 24,1898.

To all whom it may concern.-

Be it known that I, CHESTER B. ALBREE, of Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented anew and usefulImprovementin Clamps for Pipes,

Shafts, 850., of which the following is a full,

clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which Figure 1 is aperspective view of a gas-pipe joint provided with my improved splitclamp. Fig. 2 is an outer face View of one of the rings forming theclamp. Fig. 3 is an inner face view of the ring with its two partsseparated. Fig. 4 is an edge or top plan view of one of the rings inplace, and Fig. 5 is a broken end elevation showing the offset lug.

My invention relates to the split clamps employed in connection withpipes or shafts for compressing a gasket against acompressionsurfacethereon; and it is designed to provide an improved construction of thering-joint, whereby the joint is strengthened and prevented from bendingor bowing outwardly, so as to prevent the desired compression of thegasket at such point.

In the drawings, in which I show my device as employed for apacking-clamp at a pipejoint, 2 2 represent the two rings forming theclamp, these being drawn toward each other by the connecting-bolts 3.Each of these rings consists of two parts, each similar to the other andhaving at one end a projecting lip 5 in the plane of the ring. At theother end each ring portion is provided with an outer lip or lug 6,which is struck up or ofiset from the body a distance substantiallyequal to the thickness of the ring-body. This lip or lug is not splitaway from the body, butis joined to it by an integral curved ribbedportion, which serves to strengthen this portion rather than weaken it.The lips or lugs at both ends are provided with bolt-holes, and when thetwo parts are matched together about a pipe or shaft, one part beingreversed in position to that of the other, the bolt-holes are broughtinto registry and bolts passed therethrough, so as to draw the two ringstowardeach other and compress the gaskets.

The parts of the rings are preferably made Serial No. 684,355. (Nomodel.)

by rolling a suitable shape with a flange? at one edge thereof and thencutting this shape into suitable lengths and bending themintosemicircular form. The end portions are then out to form the lugs orlips, and the lug at one end is struck up or offset sidewise by means ofdies or hammer. i

The advantages of my invention result from the use'of the lug'which isstruck up from the body of the metal, the inner face and the adjacent,part of the side face upon the ring nextto the offset lug being flush atthe joint,

since an even uniform pressure is obtained .upon all parts of thegasket, and the lug at the joint is prevented from bending or otherdistortion. v

The ring may be split at only one point or may be formed in more thantwo parts, and other variations in the form of the ring and the jointmay be made without departing from myinvention.

1. A split clamp of forgeable metal, consist ing of sections, eachhaving at its joint with the other, a circular struck-up lug, oflsetsidewise from the body, said lug being connected with the body by acontinuous bent rib portion extending along that part of the offsetadjoining the body, whereby a flush face is obtained at the joints, andthe joints can open and close in one and the same plane; substantiallyas described. 4 2. A split clamp of forgeable metal, consisting ofsections, each having at its joint with the other, a circular struck-uplug, offset side wise from the body, and extending only partly acrossthe body, said lug being connected with the body by a continuous bentrib portion extending along that part of the ofiset adjoining the body,whereby a flush face is obtained at the joints, and the joints can openand close in one and the same plane; substantially as described.

In testimony whereof I have hereunto set my hand.
